    Help! I just replaced my Blue crt and HOT. TV is up but, alignment is
    being difficult. When I goto DOTS the BLUE horizontal size seems too
    far at corners! Is this a trim pot setting or a lens adjustment on the
    top of the crt.

    Model # and chassis is still important.

    Two reasons this could give you problems:

    Centering rings assembly was not positioned correctly or wrong CRT
    assembly (!!), I've had RCA send us a new CRT that was for 46" to
    replace coolant leaking 52" CRT. The box wrong CRT came in had
    correct part number (!?). Needless to say, the mounting flange was
    designed to not fit and also has clear markings (cast into the alloy
    flange as "46", "52" or "62". Whew!

    On newer Samsung projector sets for example doesn't use centering
    rings which is measure of cost-cutting and is cheap way out.
